This guide builds on my own knowledge and inputs from various discussions and guides from other forums. This guide would not have been possible without all these inputs, so consider this guide as a work of the SWTOR forum, instead of the work of a single player.

About myself, I am NeNiMel of The Red Eclipse. I have been playing as a mercenary healer almost since launch of this game, so I do have a decent amount of experience about what to do and not to do. I have personally tried out everything that I put into this guide, to ensure that it works in practice and not just in theory.

I would like to hear your feedback, especially if there are any additions or something you disagree with in the guide. The feedback is useful, so I can keep the guide up to date
I will in the guide refer to allies that are being healed as "targets", just to avoid any confusion.

The primary resource is called heat and the secondary resource is called Supercharge. The heat resource differs a bit form other resources because low heat-level means plenty resources and high heat-level means few resources.
The rate at which heat is vented is dependent on the heat-level. The higher heat-level the slower resources are being regenerated. The regeneration tiers are with 0 alacrity:

0-40 Heat: 5 Heat/second (Fast)

41-80 Heat: 3 Heat/Second (Moderate/Slow)

81-100 Heat: 2 Heat/Second (Very slow)

A mercenary healer should try to stay in the fast region as often as possible to maximize the output.

Gyroscopic Alignment Jets
You vent 10 heat when stunned, immobilized, knocked down or otherwise incapacitated. Situational – This utility is only useful if there is a lot of cc mechanics in the fight.

Improved Vents
Vent Heat now immediately vents an additional 15 heat and grants 10% alacrity for 6 seconds. Essential – The additional heat vented and alacrity buff is a must have for PvE content

Power Barrier
Power Shot, Tracer Missile and Rapid Scan generates a Power Barrier that increases damage reduction by 1% for 15 seconds. Stacks up to 5 times. Recommended – It will be impossible to keep 100% uptime on this utility, but it is still better than the alternatives

Jet Escape
Reduces the cooldown of Jet Boost by 5 seconds and Determination by 30 seconds. Situational – In some fights, determination is useful to get out of harm’s way and therefore this utility gets handy

Torque Boosters
Increases the duration of Hydraulic Overrides by 4 seconds. Situational – Will only be useful in movement heavy fights

Suit FOE
When you activate Cure on yourself, a Foreign Object Excisor reduces all periodic damage taken by 30% for 12 seconds. Almost Worthless – Only useable on self, so mostly a PvP utility

Protective Field
Increases all healing received by 20% while Energy Shield is active. Situational – Will increase the survivability chance in fights where there might be focus damage on you or in fight with heavy burn phases.

Power Shield
Energy Shield now further decreases ability activation pushback by 30% and makes you immune to interrupts. Recommended – Makes you immune to activation pushback when Energy Shield is active, which is very useful in burn phases and AoE heavy fights.

Pyro Shield
When activated, your Energy Shield ignites in a blaze, lashing attackers for xzy elemental damage while it remains active. This effect cannot occur more than once each second. Situational – Only take this if: 1) You take damage over a longer period. 2) You can heal through that damage.

Heat Damping
Eliminates the heat generated by Jet Boost, Concussion Missile, Cure and Electro Dart. Situational – Can be useful in fights with cleansing to help heat management

Infrared Sensors
Increases stealth detection level by 2, melee and ranged defense by 2% and reduces the cooldown of Stealth Scan by 5 seconds. Situational – The stealth boost is useless! Take this utility for the passive defence boost if there is nothing else

Energy Rebounder
When you take damage, the active cooldown of Energy Shield is reduced by 3 seconds. This effect connot occur more than once every 1.5 seconds. In addition, when you take damage, you have a 20% chance to emit an Energy Redoubt, which absorbs a low amount of damage and lasts 6 seconds. This effect cannot occur more than once every 10 seconds. Situational – If you are taking a lot of unavoidable damage during most of the fight, take this!

Jet Rebounder
Increases the damage dealt by Jet Boost by 30%. In addition taking damage reduces the active cooldown of Jet boost by 1 second. This effect cannot occur more than once every 1.5 seconds. Worthless – Never take this!

Kolto Jets
Jet Boost heals you and up to 7 other allies within range for xyz-xzy. Almost Worthless – The amount of healing from this is too low to be worth it

Thrill of the Hunt
Allows Unload, Blazing Bolts and Progressive Scan to be activated while moving. Recommended – This skill is a must have for most fights, because it increases the mobility. If you can stand still most of the fight do not take this utility

Stabilized Armor
Reduces damage taken from area effects by 30%. Additionally, while stunned, you take 30% less damage from all sources. Recommended – Almost all fights are very AoE heavy, so this utility is probably the best Heroic.

Supercharged Reserves
Reduces the cooldown of Cure and Disabling Shot by 3 seconds each. In addition, you build up to 10 stacks of Supercharge over the course of using Recharge and Reload. This effect cannot occur more than once every 30 seconds. Situational – This skill can be useful in fights with cleansing to lower the cooldown of Cure, but is not really needed in the current fights.

Power Overrides
Reduces the cooldowns of Concussion Missile and Power Surge by 15 seconds each. In addition Power Surge grants a second charge, making your next two abilities with activation time activate instantly. Situational – This utility increases the burst healing potential and can useful in fights with high damage burst

The way the utility system works is: The player must use a minimum of 3 utility points in the skillful category to be able to use any in the masterful category. To unlock the heroic category the sum of the utility points in the skillful and masterful category must be minimum 5.

The entire system makes the build very customizable, so dependent on the fight and personal play styles the setup will differ a lot. Because of this, one build will not be optimal for all fights and for all players.

Supercharged Gas
Supercharged Gas is still one of the core abilities in the mercenary rotation even after it has been nerfed in 3.0. The ability provides great burst healing potential or works as a rolling buff that should be kept up as often as possible:

Heat management
When Supercharged Gas is being activated it vents 10 heat.

General healing buff
When Supercharged Gas is being activated it consumes all 10 stacks of supercharge and thereby removing the +1% healing buff from these. Instead, Supercharged Gas will provide a stronger healing buff during its duration that will increase all healing done by +5%.

Healing Scan buff
Supercharged Gas will lower the heat cost, reset and remove the cooldown on Healing Scan while it is active. Increasing the burst potential greatly.

Under normal circumstances, Supercharged Gas should be used whenever it is ready, but in some fights, it is better to hold it for a few seconds to be ready for a coming burst healing phase.

Hint! In 3.0 it is still possible to build stacks of supercharge while Supercharged Gas is active!

Kolto Shell
The Kolto Shell will provide a continuous, passive healing to the target when it takes damage and is therefore extremely helpful for the heat management. The Kolto Shell should be applied to as many targets as possible during a fight to lower the overall damage taken by the raid.

The Kolto Shell is extremely effective in fights with a lot of raid wide damage and in these fights; the mercenary healer should focus on blanketing the raid with Kolto Shell, whenever there are no more pressing matters to attend.

It might not always be possible to keep 100% uptime on all raid members during the entire fight, especially in 16man. In these cases, it is good to have a priority on who will benefit most from a Kolto Shell. The priority will be based on who takes the most damage during a fight and will in most cases look something like this:

Tanks

Melee DPS

Healers

Ranged DPS

It is important, not to reapply the Kolto Shell on a target unless the old one is depleted (or very near depleted), because if it is reapplied too often the full potential is not used and the heat-level will most likely go out of hand. The Kolto Shell should as a minimum be kept up on the tanks at all time.

Progressive Scan
Progressive Scan is one of the most useful abilities in the repertoire and should be used as often as possible. The primary reason for this is the armor buff that it applies to the four targets it heals over the channeled duration that increases the armor by 10%. Besides the armor buff the heal itself is very effective because it will always heal the targets with the lowest health.

Rapid Scan
Rapid Scan’s primary function, besides healing, is to build 1 stack of Critical Efficiency each time it is used. Each stack of Critical Efficiency reduces the heat-cost of Healing Scan by 5 and it stacks up to 3 times. Rapid Scan is therefore an important ability help with heat management.
Besides that Rapid Scan also builds 2 stacks of supercharge each time it is used.

Hint! If talented Rapid Scan also builds 1 stack of Power Barrier

Healing Scan
Healing Scan is the strongest healing ability in the rotation. The primary function of the ability is to provide a +3% healing received buff to the target. This healing buff should as a minimum be kept up on the tanks at all time, but the buff should be applied to as many targets as possible during the fight.

Hint! During Supercharged Gas, Healing Scan has no cooldown and can be cast on a lot of people in very short time (OBS watch your heat).

Emergency Scan
Emergency Scan is the primary burst heal, because not only it activates instantly, but also because it makes the next Healing Scan activate instantly. Besides the initial burst healing Emergency Scan also provides a HoT that heals for a fair amount.

Emergency Scan and Healing Scan should in most cases be used together, but not necessarily at the same target. The instant cast of Healing Scan after Emergency Scan can be used to fast apply the healing received buff to more targets.

Kolto Shot
Kolto Shot is used as a filler in the rotation whenever only a low to moderate amount of healing is needed. Kolto Shot will also help with heat-management since it will vent 1 heat (2, if critical) and build 1 stack of supercharge each time it is used. Therefore Kolto Shot is a very important ability and should be used whenever no bigger heals are needed.

Kolto missile
Kolto Missile is the mercenary’s primary AoE heal. So if the fight has a lot or raid damage Kolto Missile should be used as often as possible. Kolto Missile is maybe the strongest AoE heal in the game at the moment due to the short cooldown and relatively high output. Note that Kolto Missile also can be cast on the run.

Progressive Scan
Progressive Scan is also very effective for raid healing, because it heals up to four targets over the channel duration.

Hint! Progressive scan can also be cast on the run if Thrill of the Hunt utility is selected.

Jet Boost
Jet Boost can also be used as a AoE heal if Kolto Jets utility is selected. Jet Boost heals all allies around your current position for a moderate amount. When using Jet Boost as a AoE heal there are a few things to consider:

High cooldown
Jet Boost has a high cooldown and can therefore only be used a few times during a fight.

It is difficult to position
Jet Boost is a nice AoE heal ability, but do not use a lot of time moving around just to be in a better position for Jet Boost, the time is better used on other abilities. Position yourself in the middle of a group with friendly targets (often together with the ranged DPS and other healers) in the start of the fight, and if any of these targets take damage, then you can use Jet Boost to heal them without changing your current healing target (often the tank).

It knocks back enemies
This is often not preferred, when people are stacking and the enemies have been grouped up for AoE damage. So do not use it when adds are around.

Standard rotation
This should be used as a guideline for how to prioritize the abilities in a standard situation. The abilities are listed after importance and should not be executed top-down, instead abilities with higher importance should be executed more often.

Aim
Aim is the main stat for mercenary healers, since it boosts the bonus healing and increases critical chance for a small amount. Items with aim: All except relics, color crystals and enhancements

Power / Tech power
Power is important for healers, since it boosts the bonus healing/damage. Items with power: All except barrels and armorings.

Critical rating
Critical rating increases the chances of getting a critical heal/attack, when an ability is used. Critical rating is not a linear stat, which means that the increase to critical chance will decrease with the amount of critical rating, so it is not a good idea to stack too much of it. Items with critical rating: earpieces, implants, mods, enhancements and augments.

Surge rating
Surge rating increases the magnitude of the critical heals/attacks. Like critical rating, surge rating is only valuable until a certain amount. Items with surge rating: earpieces, implants, mods, enhancements and augments.

Alacrity rating
Alacrity rating decreases the activation time of the abilities, reduces cooldown, and increases the resource regeneration rate. Like critical and surge rating, alacrity rating is only valuable until a certain amount. Items with alacrity rating: earpieces, implants, mods, enhancements and augments.

Aim or power?
There is always a discussion on whether mainstat or power is better for healing. Power gives a slightly higher direct healing bonus than aim and is therefore more preferable for healers in many cases. However mercenary healers have a higher critical multiplier (surge rating) than any other class in the game, due to the two passives “Warden” and “Advanced Targeting”. Because of this higher critical multiplier aim might be slightly better than power.
I personally prefer to use reflex augments to boost my critical chance a bit, but still like to have a lot of power on my mods (which is the other place you will have to decide between aim or power).

Power or critical rating?
The balance between power and critical rating is mostly up to personal preferences. Both critical rating and power increases the expected healing output with a fair amount and none of them should be omitted.
I personally prefer to run with a critical rating just below the theoretical optimum and thereby have a bit more power, because I prefer the size of my heals to be a bit more predictable. By deviating from the optimum critical rating the expected output will be bit lower, but only by a small amount.

Surge rating or alacrity rating?
Surge and alacrity are both extremely useful stats for healers, but it is not a good idea to stack too much surge because the value decreases drastically at higher values. Therefore, I personally focus on getting more alacrity than surge. I would recommend going for 3 surge pieces and 7 alacrity pieces, but 4 and 6 respectively would also work.

Set Bonuses
The set bonuses are very important for mercenary healers, because they will greatly increase the healing output:

2-piece: Activating a healing ability has a 15 percent chance to grant Combat Medic’s Critical Bonus which causes your next Rapid Scan or Medical Probe to be a critical. This effect can only occur once every 30 seconds.
4-piece: While in Combat Cylinder or Combat Support Cell the duration of Supercharged Gas and Supercharged Cells is increased by 5 seconds.
6-piece: Reduces the cooldown of Healing Scan or Advanced Medical Probe by 1.5 seconds.

Set-bonuses are the first thing one should focus on getting. Set-bonuses are so important that a armoring with the bonus is better than a armoring two gear tiers higher that does not have the bonus.

Theory and Interactive Model
Orderken have made an interactive model that can give a better understanding of how the different stats affects ones output theoretically. The model can be very useful for gearing optimization.
The model can be found at the following link:https://onedrive.live.com/redir?resi...nt=file%2cxlsx

I have included both power and alacrity adrenal, since both can be useful dependent on the fight. Power adrenal will increase the size of your heals for a short period and alacrity adrenals will allow you to put out more abilities for a short period. Another advantage of alacrity adrenal is that they can be used for heat management (Increases the regeneration), but that should not be the primary reason to use it.

Datacrons
Datacrons provides a small permanent boost to the primary stats (aim, cunning, endurance, strengh and willpower). The datacrons can also give you datashards, but these are of little use since the datacube is no longer BiS relic.

The datacrons that the bounty hunter should focus on collecting are the aim, cunning and endurance ones. The reason for for collecting cunning datacrons too is because cunning boosts the tech critrate with a small amount.

These buffs can only be achieved once per legacy, so you only have to max out the affection with each companion type on one character.
The buffs relevant for the mercenary healer is Increased critical chance, critical multiplier, healing received and HP. The accuracy buff is only relavant for DPS.

VI. User interfaceBack to Table of Content
The user interface is a very important part for healers, since you can increase the healing done a lot, by just setting it up correctly. The optimal user interface differs from player to player, but I will try to cover the basics here.

Graphical user interface
First of all the normal group window should be changed the ops-window (can be done in preferences), since the character pictures are just a waste of space in the graphical interface.
The ops-window and the health bars inside it should be as large as possible, since healers have to focus mostly on the group’s health and not so much the battleground itself. By making the opswindow large also makes it, easier to spot debuffs on the friendly targets. It is also possible in the options for the ops-window to only display cleansable debuffs if one prefer that.
By increasing the maximum zoom in the preferences you can get a better view over the battlefield. This will help a lot when placing an AoE heal.

One thing should be done by all healers is to focus target the boss to easily see how much health the boss has left and to see what skills the boss is casting (interrupt if it´s possible and if there is time).

Controls
Assign hotkeys to the abilities that is most frequently used. This might be obvious to most people, but I have met several people that did not use hotkeys, and was surprised how much it helped them, when they started using them. Place the hotkeys close the movement buttons, so they are close at hand (I use the number just above the letters).

In the preferences, there are a set of options that can be extremely useful for healers. These options can be found under Preferences -> Controls -> Combat:

Action Queue
By using this option, you will be able to queue up the abilities you want to cast and thereby minimizing the delay between each action (increasing the APM). This is very useful for burst healing.

Sticky Ground Target Reticule
When this option is enabled, your ground target telegram does not disappear if the target location is out of range or the ability otherwise fails.

Quick Ground Target Activation
When this option is enabled, you will be able to cast AOE abilities by just double tapping the hot key. The target location will be your current target. This option is very useful when you are moving around and do not have time place your Kolto Missile / Kolto Bomb.

VII. ConclusionBack to Table of Content
Healing as a mercenary is both fun and challenging, since a mercenaries have this special heat mechanism that makes it play-style unique. The most important part for mercenaries is to learn how to control the heat-level and since most boss fight have different mechanisms the optimal rotation might differ a lot from the standard rotation.

I hope that you find this guide useful and want to try out as a mercenary healer sometime

TOR Community and Dulfy
Thanks The Old Republic Community and Dulfy for providing the tools used in gear section and the utility section of the guide.

The primary resource is called energy cells and the secondary resource is called Supercharge.
The rate at which energy cells are regenerated is dependent on the current energy cell-level. The higher energy cell-level the slower resources are being regenerated. The regeneration tiers are with 0 alacrity:

100-60 Energy Cells: 5 Cells/second (Fast)

59-20 Energy Cells: 3 Cells/Second (Moderate/Slow)

19-0 Energy Cells: 2 Cells/Second (Very slow)

A commando healer should try to stay in the fast region as often as possible to maximize the output.

Parallactic Combat Stim
You recharge 10 energy cells when stunned, immobilized, knocked down or otherwise incapacitated. Situational – This utility is only useful if there is a lot of cc mechanics in the fight.

Charged Barrier
Charged Bolts, Grav Round and Medical Probe build a Charged Barrier that reduces the damage taken by 1% for 15 seconds. Stacks up to 5 times. Recommended – It will be impossible to keep 100% uptime on this utility, but it is still better than the alternatives

Tenacious Defense
Reduces the cooldown of Concussion Charge by 5 seconds and Tenacity by 30 seconds. Situational – In some fights, Tenacity is useful to get out of harm’s way and therefore this utility gets handy

Advance the Line
Increases the duration of Hold the Line by 4 seconds. Situational – Will only be useful in movement heavy fights

Suit FOE
When you activate Field Aid on yourself, a Foreign Object Excisor reduces all periodic damage taken by 30% for 12 seconds. Almost Worthless – Only useable on self, so mostly a PvP utility

Med Zone
Increases all healing received by 20% while Reactive Shield is active. Situational – Will increase the survivability chance in fights where there might be focus damage on you or in fight with heavy burn phases.

Combat Shield
Reactive Shield now further decreases ability activation pushback by 30% and makes you immune to interrupts. Recommended – Makes you immune to activation pushback when Reactive Shield is active, which is very useful in burn phases and AoE heavy fights.

Electro Shield
When activated, your Reactive Shield charges with electricity, zapping attackers for xzy elemental damage while it remains active. This effect cannot occur more than once each second. Situational – Only take this if: 1) You take damage over a longer period. 2) You can heal through that damage.

Efficient Conversions
Removes the energy cell cost of Concussion Charge, Concussion Round, Field Aid and Cryo Grenade. Situational – Can be useful in fights with cleansing to help energy cell management

Nightvision Scope
Increases stealth detection level by 2, melee and ranged defense by 2% and reduces the cooldown of Stealth Scan by 5 seconds. Situational – The stealth boost is useless! Take this utility for the passive defence boost if there is nothing else

Reflextive Shield
When you take damage, the active cooldown of Reactive Shield is reduced by 3 seconds. This effect connot occur more than once every 1.5 seconds. In addition, when you take damage, you have a 20% chance to emit an Energy Redoubt, which absorbs a low amount of damage and lasts 6 seconds. This effect cannot occur more than once every 10 seconds. Situational – If you are taking a lot of unavoidable damage during most of the fight, take this!

Reflexive Battery
Increases the damage dealt by Concussion Charge by 30%. In addition taking damage reduces the active cooldown of Concussion Charge by 1 second. This effect cannot occur more than once every 1.5 seconds. Worthless – Never take this!

Kolto Wave
Concussion Charge heals you and up to 7 other allies within range for xyz-xzy. Almost Worthless – The amount of healing from this is too low to be worth it

Forced March
Allows Full Auto, Boltstorm and Successive Treatment to be activated while moving. Recommended – This skill is a must have for most fights, because it increases the mobility. If you can stand still most of the fight do not take this utility

Shock Absorbers
Reduces damage taken from area effects by 30%. Additionally, while stunned, you take 30% less damage from all sources. Recommended – Almost all fights are very AoE heavy, so this utility is probably the best Heroic.

Supercharged Reserves
Reduces the cooldown of Field Aid and Disabling Shot by 3 seconds each. In addition, you build up to 10 stacks of Supercharge over the course of using Recharge and Reload. This effect cannot occur more than once every 30 seconds. Situational – This skill can be useful in fights with cleansing to lower the cooldown of Field Aid, but is not really needed in the current fights.

Overclock
Reduces the cooldowns of Concussion Round and Tech Override by 15 seconds each. In addition Tech Override grants a second charge, making your next two abilities with activation time activate instantly. Situational – This utility increases the burst healing potential and can useful in fights with high damage burst

The way the utility system works is: The player must use a minimum of 3 utility points in the skillful category to be able to use any in the masterful category. To unlock the heroic category the sum of the utility points in the skillful and masterful category must be minimum 5.

The entire system makes the build very customizable, so dependent on the fight and personal play styles the setup will differ a lot. Because of this, one build will not be optimal for all fights or all players.

Supercharged Cells
Supercharged Cells is still one of the core abilities in the commando rotation even after it has been nerfed in 3.0. The ability provides great burst healing potential or works as a rolling buff that should be kept up as often as possible:

General healing buff
When Supercharged Cells is being activated it consumes all 10 stacks of supercharge and thereby removing the +1% healing buff from these. Instead, Supercharge Cell will provide a stronger healing buff during its duration that will increase all healing done by +5%.

Advanced Medical Probe buff
Supercharged Cells will lower the energy cell cost, reset and remove the cooldown on Advanced Medical Probe while it is active. Increasing the burst potential greatly.

Under normal circumstances, Supercharged Cells should be used whenever it is ready, but in some fights, it is better to hold it for a few seconds to be ready for a coming burst healing phase.

Hint! In 3.0 it is still possible to build stacks of supercharge while Supercharged Cells is active!

Trauma Probe
The Trauma Probe will provide a continuous, passive healing to the target when it takes damage and is therefore extremely helpful for the energy management. The Trauma Probe should be applied to as many targets as possible during a fight to lower the overall damage taken by the raid.

The Trauma Probe is extremely effective in fights with a lot of raid wide damage and in these fights; the commando healer should focus on blanketing the raid with Trauma Probes, whenever there are no more pressing matters to attend.

It might not always be possible to keep 100% uptime on all raid members during the entire fight, especially in 16man. In these cases, it is good to have a priority on who will benefit most from a Trauma Probe. The priority will be based on who takes the most damage during a fight and will in most cases look something like this:

Tanks

Melee DPS

Healers

Ranged DPS

It is important, not to reapply the Trauma Probe on a target unless the old one is depleted (or very near depleted), because if it is reapplied too often the full potential is not used and the energy management will go out of hand. The Trauma Probe should as a minimum be kept up on the tanks at all time.

Successive Treatment
Successive Treatment is one of the most useful abilities in the repertoire and should be used as often as possible. The primary reason for this is the armor buff that it applies to the four targets it heals over the channeled duration that increases the armor by 10%. Besides the armor buff the heal itself is very effective because it will always heal the targets with the lowest health.

Medical Probe
Medical Probe’s primary function, besides healing, is to build 1 stack of Field Triage each time it is used. Each stack of Field Triage reduces the energy-cost of the next Advanced Medical Probe by 5 and it stacks up to 3 times. Medical Probe is therefore an important ability help with energy management.
Besides that Medical Probe also builds 2 stacks of supercharge each time it is used.

Advanced Medical Probe
Advanced Medical Probe is the strongest healing ability in the rotation. The primary function of the ability is to provide a +3% healing received buff to the target. This healing buff should as a minimum be kept up on the tanks at all time, but the buff should be applied to as many targets as possible during the fight.

Hint! During Supercharged Cells, Advanced Medical Probe has no cooldown and can be cast on a lot of people in very short time (OBS watch your energy).

Bacta Infusion
Bacta Infusion is the primary burst heal, because not only it activates instantly, but also because it makes the next Advanced Medical Probe activate instantly. Besides the initial burst healing Bacta Infusion also provides a HoT that heals for a fair amount.

Bacta Infusion and Advanced Medical Probe should in most cases be used together, but not necessarily at the same target. The instant cast of Advanced Medical Probe after Bacta Infusion can be used to fast apply the healing received buff to more targets.

Med Shot
Med Shot is used as a filler in the rotation whenever only a low to moderate amount of healing is needed. Med Shot will also help with energy-management since it will recharge 1 energy cell (2, if critical) and build 1 stack of supercharge each time it is used. Therefore Med Shot is a very important ability and should be used whenever no bigger heals are needed.

Kolto Bomb
Kolto Bomb is the commando’s primary AoE heal. So if the fight has a lot or raid damage Kolto Bomb should be used as often as possible. Kolto Bomb is maybe the strongest AoE heal in the game at the moment due to the short cooldown and relatively high output. Note that Kolto Bomb also can be cast on the run.

Successive Treatment
Successive Treament is also very effective for raid healing, because it heals up to four targets over the channel duration.

Hint! Successive Treament can also be cast on the run if Forced March utility is selected.

Concussion Charge
Concussion Charge can also be used as a AoE heal if Kolto Wave utility is selected. Concussion Charge heals all allies around your current position for a moderate amount. When using Concussion Charge as a AoE heal there are a few things to consider:

High cooldown
Concussion Charge has a high cooldown and can therefore only be used a few times during a fight.

It is difficult to position
Concussion Charge is a nice AoE heal ability, but do not use a lot of time moving around just to be in a better position for Concussion Charge, the time is better used on other abilities. Position yourself in the middle of a group with friendly targets (often together with the ranged DPS and other healers) in the start of the fight, and if any of these targets take damage, then you can use Concussion Charge to heal them without changing your current healing target (often the tank).

It knocks back enemies
This is often not preferred, when people are stacking and the enemies have been grouped up for AoE damage. So do not use it when adds are around.

Standard rotation
This should be used as a guideline for how to prioritize the abilities in a standard situation. The abilities are listed after importance and should not be executed top-down, instead abilities with higher importance should be executed more often.

Aim
Aim is the main stat for commando healers, since it boosts the bonus healing and increases critical chance for a small amount. Items with aim: All except relics, color crystals and enhancements

Power / Tech power
Power is important for healers, since it boosts the bonus healing/damage. Items with power: All except barrels and armorings.

Critical rating
Critical rating increases the chances of getting a critical heal/attack, when an ability is used. Critical rating is not a linear stat, which means that the increase to critical chance will decrease with the amount of critical rating, so it is not a good idea to stack too much of it. Items with critical rating: earpieces, implants, mods, enhancements and augments.

Surge rating
Surge rating increases the magnitude of the critical heals/attacks. Like critical rating, surge rating is only valuable until a certain amount. Items with surge rating: earpieces, implants, mods, enhancements and augments.

Alacrity rating
Alacrity rating decreases the activation time of the abilities, reduces cooldown, and increases the resource regeneration rate. Like critical and surge rating, alacrity rating is only valuable until a certain amount. Items with alacrity rating: earpieces, implants, mods, enhancements and augments.

Aim or power?
There is always a discussion on whether mainstat or power is better for healing. Power gives a slightly higher direct healing bonus than aim and is therefore more preferable for healers in many cases. However commando healers have a higher critical multiplier (surge rating) than any other class in the game, due to the two passives “Potent Medicine” and “Target Lock”. Because of this higher critical multiplier aim might be slightly better than power.
I personally prefer to use reflex augments to boost my critical chance a bit, but still like to have a lot of power on my mods (which is the other place you will have to decide between aim or power).

Power or critical rating?
The balance between power and critical rating is mostly up to personal preferences. Both critical rating and power increases the expected healing output with a fair amount and none of them should be omitted.
I personally prefer to run with a critical rating just below the theoretical optimum and thereby have a bit more power, because I prefer the size of my heals to be a bit more predictable. By deviating from the optimum critical rating the expected output will be bit lower, but only by a small amount.

Surge rating or alacrity rating?
Surge and alacrity are both extremely useful stats for healers, but it is not a good idea to stack too much surge because the value decreases drastically at higher values. Therefore, I personally focus on getting more alacrity than surge. I would recommend going for 3 surge pieces and 7 alacrity pieces, but 4 and 6 respectively would also work.

Set Bonuses
The set bonuses are very important for commando healers, because they will greatly increase the healing output:

2-piece: Activating a healing ability has a 15 percent chance to grant Combat Medic’s Critical Bonus which causes your next Rapid Scan or Medical Probe to be a critical. This effect can only occur once every 30 seconds.
4-piece: While in Combat Cylinder or Combat Support Cell the duration of Supercharged Gas and Supercharged Cells is increased by 5 seconds.
6-piece: Reduces the cooldown of Healing Scan or Advanced Medical Probe by 1.5 seconds.

Set-bonuses are the first thing one should focus on getting. Set-bonuses are so important that a armoring with the bonus is better than an armoring two gear tiers higher that does not have the bonus.

Theory and Interactive Model
Orderken have made an interactive model that can give a better understanding of how the different stats affects ones output theoretically. The model can be very useful for gearing optimization.
The model can be found at the following link:https://onedrive.live.com/redir?resi...nt=file%2cxlsx

I have included both power and alacrity adrenal, since both can be useful dependent on the fight. Power adrenal will increase the size of your heals for a short period and alacrity adrenals will allow you to put out more abilities for a short period. Another advantage of alacrity adrenal is that they can be used for energy management (Increases the regeneration), but that should not be the primary reason to use it.

Datacrons
Datacrons provides a small permanent boost to the primary stats (aim, cunning, endurance, strengh and willpower). The datacrons can also give you datashards, but these are of little use since the datacube is no longer BiS relic.

The datacrons that the Trooper should focus on collecting are the aim, cunning and endurance ones. The reason for for collecting cunning datacrons too is because cunning boosts the tech critrate with a small amount.

These buffs can only be achieved once per legacy, so you only have to max out the affection with each companion type on one character.
The buffs relevant for the commando healer is Increased critical chance, critical multiplier, healing received and HP. The accuracy buff is only relavant for DPS.

V. User interfaceBack to Table of Content
The user interface is a very important part for healers, since you can increase the healing done a lot, by just setting it up correctly. The optimal user interface differs from player to player, but I will try to cover the basics here.

Graphical user interface
First of all the normal group window should be changed the ops-window (can be done in preferences), since the character pictures are just a waste of space in the graphical interface.
The ops-window and the health bars inside it should be as large as possible, since healers have to focus mostly on the group’s health and not so much the battleground itself. By making the ops-window large also makes it, easier to spot debuffs on the friendly targets. It is also possible in the options for the ops-window to only display cleansable debuffs if one prefer that.
By increasing the maximum zoom in the preferences you can get a better view over the battlefield. This will help a lot when placing an AoE heal.

One thing should be done by all healers is to focus target the boss to easily see how much health the boss has left and to see what skills the boss is casting (interrupt if it´s possible and if there is time).

Controls
Assign hotkeys to the abilities that is most frequently used. This might be obvious to most people, but I have met several people that did not use hotkeys, and was surprised how much it helped them, when they started using them. Place the hotkeys close the movement buttons, so they are close at hand (I use the number just above the letters).

In the preferences, there are a set of options that can be extremely useful for healers. These options can be found under Preferences -> Controls -> Combat:

Action Queue
By using this option, you will be able to queue up the abilities you want to cast and thereby minimizing the delay between each action (increasing the APM). This is very useful for burst healing.

Sticky Ground Target Reticule
When this option is enabled, your ground target telegram does not disappear if the target location is out of range or the ability otherwise fails.

Quick Ground Target Activation
When this option is enabled, you will be able to cast AOE abilities by just double tapping the hot key. The target location will be your current target. This option is very useful when you are moving around and do not have time place your Kolto Missile / Kolto Bomb.

Regarding a more detailed stat section am I currently working on an extension that reflects my personal stat goals. I will also update the section on BiS relics, since there have been some changes to these

I haven't seen any big change in my numbers yet, but I think its because I need to do a few minor adjustments to my playstyle.
I do think it have become a little easier to control my heat though, with more critical reaction procs. It might just be a placebo!

If you got any suggestions dont hold back! I would like to try out new ideas and playstyles

Ok, one thing i noticed is that you have different builds for different situations. you dont need that... http://www.torhead.com/skill-calc#30...cdkfGzZMccZb.3 is the only merc build you will ever need for healing. the points in Power Shield and Heat Dampening are kinda useless, unless your at a boss that uses lots of knockback. then Power Shield is semi-useful.
